| Popis | In our study we focused on description of the new species of eugregarine from Antarctic littoral amphipod. Mostly syzygies were observed, all of them were caudo-frontal. The syzygy partners were elongated and slightly curved. The contact between them looked simple. Both cells in syzygy had a granular cytoplasm and a transparent layer at the cell periphery. Electron microscopic observations revealed that parasites are covered with a typical alveolate pellicle, i.e. plasma membrane is underlain by the inner membrane complex. The pellicle forms characteristic epicytic folds that run longitudinally from one to another end of the parasite. Preliminary molecular-phylogenetic analysis of 18S rRNA gene sequence obtained from this gregarine confirm that this parasite belongs to eugregarines. Further analysis showed (as it was expected) its affiliation to the superclade Cephaloidophoroidea, described previously, which unites eugregarines from various marine and fresh-water crustaceans. |
